FEED-REGULATOR FOR GASOLENE-ENG INES.

SPECIFICATION forming part of Letters Patent No. 748,990, dated January 5, 1904. Application filed September 13, 1901. Serial No. 75,243. (No model.)

To all whom it may concern:

Be it known that we, HARRY H. SEGNER and CHARLES E. SEGNER, citizensof the United States, residing at Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Feed-Regulators for Gasolene-Engines, of which the following is a specification.

Our said invention consists in various improvements in the details of construction of attachments for feeding gasolene or other oils to explosive-engines, whereby the amount of air and gasolene may be fairly regulated to secure the proportion of one to the other required for the best results, and also to secure the most advantageous amount of. mixture for a charge, the device at the same time being of simple construction and easy adjustment, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a vertical section through a cylinder of a gasolene-engine and the oilfeeding attachment, illustrating its use, the parts being in the positionvthey occupy when the engine-piston is making a downstroke to draw in a charge of the mixture, Fig. 2, a sectional view of the feed attachment separate on an enlarged scale, the valve being in closed position; and Fig. 3 a detail cross-section on the dotted line 3 3 in Fig. 2.

In said drawings the portions marked A represent the engine-cylinder, B the body or casing of the feed attachment,and.O the valve controlling the supply of oil.

The cylinder A and its connected parts other than the feed attachment are or may be of any approved form and arrangement for an explosive-engine, being provided with an inlet-valve 1,an exhaust-valve 2,piston 3, and various other essential parts, tl1e description of which is not necessary herein, except in incidentally describing the operation of the feed attachment, which is the sole subjectmatter of this application. The body B of said attachment is cylindrical in form and is connected at its bottom with the gasolenesupply pipe &, a valve seat being formed around the entrance, on which valve G is adapted to seat. Said valve 0 is formed on the lower end of a stem 0, which extends up through the top of the body B and is provided on its top end with means for turning it, such asv a transverse pin 5. Its lower end is screw-threaded and engages with a screwthreaded perforation in a boss formed on the top of a hollow piston B. Said piston is mounted to reciprocate in the body B, but is held from turning by a pin 6-,extending therefrom down through a perforation in the bottom of said body. The bottom of said piston is providedwith a central perforation, and the bottom of the body is provided with a series of perforations p near its outer edge, the relative arrangement of the parts being such that should the piston rest upon the bottom of the body the perforations in said body would be closed. The top of said hollow piston is also provided with perforations. A spring 7 is mounted on the valve-stem O, interposed between the piston B and the top of the body. A set-screw 8 is mounted in an arch 9, extending over the top directly above and in line with the top of stem 0'. The top of the stem has a collar 10 adj ustably secured near its top by a wire l1,which passes through the perforation therein, said perforation registering with grooves in the stem with which a portion of the diameter of the wire may engage. A set-screw 12in said collar is adapted to impinge against the side of said wire and secure both the collar and Wire rigid with said valve-stem. The parts may thus be socurely held in the proper relative adj ustments. The ends of the wire extend transversely to contact with the sides of the arch 9 and hold the stem from turning.

As is well known, the success of an engine of this character in operation depends largely upon the mixture used and the charge employed. With a charge of proper quantity and composed of proper proportions of oil and air the most advantageous results are secured, the greatest power, and greatest economy in operation. By the construction shown and just described these advantages may be secured, as follows: By'the proper adjustment of set-screw 8 the distance which valve C will rise from its seat, and the consequent size of inlet-opening and quantity of gasolene admitted, can be regulated as desired. By

loosenin set-screw 12 and turnin valve-stem h O the piston B will be moved up or down, according to the direction of the motion and its position in relation to the bottom of the body B, and the air-inlet perforations p may thus be regulated to admit a greater or less quantity of air. When the desired adjustment is secured, the stem 0 is locked to collar 10 by tightening the set-screw 12 and said adjustment thus held until it is desired to change it. The spring 7 operates to normally hold valve 0 to its seat and the piston B, carried thereby, in its lowermost position. In the position shown in Fig. 1 the valve is open, the piston 3 of the engine being on its downstroke and the suction caused thereby being sufficient to open valve 1 and raise valve 0, drawing a charge of gasolene from pipe 4 and of air through the perforationsp into the hollow piston B and body B, where they mix and pass through the passage P by. the valve 1 into the cylinder A, where it is compressed by the next upstroke of the piston and at the proper time exploded by a spark made by the sparker S, as is well understood. The arrangement described enables all the adjustments to be made without opening any of the parts, the adjusting devices being conveniently located on the outside. An indicator 13 may be mounted alongside the set-screw 8, by means of which the extent of the valveopening may be seen, as will be readily understood.

Having thus fully described our said invention, what We claim as new, and desire to secure by Letters Patent, is-

1. In an explosive-engine, the combination, of the cylinder, the feed attach men t, connected thereto by a passage, comprising a chamber having an oil-inlet and an air-inlet at one end, a valve for said oil-inlet provided with a stem extending through said chamber, a hollow piston adj ustably mounted on said stem with its lower end formed to cover the air-inlet openings and provided with a central opening Within the line of said air-inlet openings, and openings in its upper side, whereby the quantity of air and oil admitted may be regulated to the proper relative proportions, substantially as set forth.

2. In a feeding attachment for oil-engines, the combination, of the body having an oil and an air inlet, a reciprocating valve for the oil-inlet, a perforated piston mounted thereon by a screw-threaded connection, means for preventing it from turning, the stem of said valve extending to the outside where it is connected with means for preventing it from turning, and means for normally holding the valve closed, substantially as set forth.

3. In combination with an oilengine, a feeding attachment comprising a body provided with an oil and an air inlet, a valve for closing the oil-inlet, a piston formed with openings and adjustably mounted on the stem of said valve and adapted to extend over the air-inlet, means for preventing it from turning, the stem of said valve being extended to the outside and connected with a sliding device to which it may be locked to prevent it from turning, and an adjustable stop for limiting the opening movement of the valve, substantially as set forth.

In witness whereof we have hereunto set our hands and seals, at Hagerstown, Maryland, this 26th day of July, A. D. 1901.
